a fixing member 50 which is combined at the front end of the central shaft 17 in order to fix the coil spring 40.

Mode for the Invention

A preferred embodiment of the invention will be described in detail below by referring to the accompanying drawings. FIG. 1 is a dissembled perspective view of head slant adjuster for gold club according to a first embodiment of the invention, FIG. 2 is a perspective view showing the embodiment of FIG. 1, FIG. 3 is a cross sectional view of FIG. 2, FIG. 4 is a dissembled perspective view showing a second embodiment of the invention, and FIG. 5 is a dissembled perspective view showing a third embodiment of the invention.

As shown in FIG. 1 to FIG. 3, the golf club has a club head body 10, a neck 20 and a shaft 30. And, the club head body 10 has a face 11 which is formed at the front side for hitting a golf ball, a crown 12 which is connected with the face 11 and is formed at the upper sided, and a soul 13 which connects the face 11 with the crown 12 and faces a ground.

The invention has basically the configuration wherein a club head body 10 is combined with a neck 20. And, a hole 14 penetrates through the center of the club head body 10, and an enlarged hole 15 is formed at the front end of the club head body 10.

The enlarged hole 15 is connected with the hole 14.

A first and a second irregularity 16, 26 are formed in gear type and they are respectively formed at the rear side of the club head body 10 and the front side of the neck 20.

A central shaft 17 is projected from the front center of the neck 20 and it may be inserted into the hole 14.

And, a coil spring 40 is inserted into the front end of the central shaft 17 through the enlarged hole 15 after the central shaft 17 of the neck 20 is inserted into the hole 14, and a fixing member 50 is combined at the front end of the central shaft 17 in order to fix the coil spring 40.

Here, the fixing member 50 is preferably a snap ring, however, it may be a nut and etc. Reference number 60 is a washer.

According to the invention shown in FIG. 3, the first irregularity 16 and the second irregularity 29 are combined together in gear type, and the club head body 10 is stuck fast to the neck 20 by elastic force of the coil spring 40.

Accordingly, the slanting degree of the face 11 may be adjusted if the player lets go off the club head body 10 at the state that he/she grips the neck 20 by one hand and pulls the club head body 10 by another hand. When the player pulls the club head body 10, the coil spring 40 is shrunk and the first and the second irregularity 16, 26 are disengaged so that he/she may rotate the club head body 10. Here, if the player rotates the club head body 10 clockwise about the ground, the angle of the face 11 grows smaller. On the other hand, if the player rotates the club head body 10 counterclockwise about the ground, the angle of the face 11 grows larger.

Like the above, if the player adjusts the angle of the club head body 10 and lets go off it, the first and the second irregularity 16,26 are engaged together by the elastic force of the coil spring 40 so that the player may use the invention as a normal golf club.

And, FIG. 4 shows a second embodiment of the invention, and the function of FIG. 4 is as same as that of the first embodiment of the invention. However, it is a different point that a hole 24 and an enlarged hole 25 are formed at a neck 20 and a central shaft 27 is formed at a club head body 10. Further, the using method of FIG. 4 is as same as that of the first embodiment.

And, FIG. 5 shows a third embodiment of the invention, and the function of FIG. 5 is as same as that of the first embodiment. However, it is a different point that the hole 14 is formed in cone shape, the first irregularity 16 is formed at the inner surface of the hole 14, the central shaft 17 is formed in cone shape, and the second irregularity 26 is formed at the outer surface of the central shaft 17.

It does not matter the second irregularity 26 is formed at the whole portion or the partial portion of the central shaft 17, and the second irregularity 26 is engaged with the first irregularity 16 of the hole 14. Further, the using method of FIG. 5 is as same as that of the first embodiment.

Industrial Applicability

As described above, the invention has an advantage that the player may use conveniently by adjusting the angle of golf club head the manufacture is easy. And, the invention is convenient for the users to carry with them and do not cause the user economical burden.
